Well my reason for using it will be a few... one for the same benefits as drip clean.... another would be a high p booster during transition(first 2 weeks of flower to promote more bud sites)...
Ideally I use my base nutes at 500-600ppm and up the ppm to 700-750 with the booster.... feed every watering ...
So I dint want to abandon the mkp... more so add the 2 together.. like 100ppm mkp and 50ppm pekacid...
My fkower base nutes have more than enough K (14-5-38) and is low in P ... but after transition K is used more than P...
This is a new recipe from a long time commercial grower I decided to try.... I've seen his product and it's pure fire so I know the recipe works and he is consistently getting 2.5 per light
It is a compound to help farmers who irrigate with high alkaline water sources. Unless you have high alkalinity in your water there is no need for it. Unless of course you are battling high Ph rise in your media.While I realize that the p and k are not the same values... I'm wondering if anyone has used pekacid in ther grow in bloom? As an addition to mkp?
I know pekacid is the commercial form of drip clean and clearex and other brands... so I know the benefits it has... I'm just wondering if anyone has incorporated it into ther fertilizer program as a P/k booster as well? (Yes I know still would need added K to balance out)
I use monopotassium phosphate. 1gram per 5 gal gives about 50ppm of P and 60ppm of K so you can just calculate what your goal is based on your base nutes. Very easy to find and cheap as hell. If you need to add more k to balance it out and you use RO water you could always go with potassium bicarbonate as a buffer. Never used pekacid before.
Interesting thought though. Keep us updated if you try.
I use a program called hydrobuddy it take the source and will calculate concentrates and direct addition amounts by weight, volume and ppm etc. It takes into account the availability of the source used. You can also just out it the ppm for any and all nutrients and then hit calculate and it will use the nutrients you have in whatever form and give you how much of each to out in by weight or volume. It will also calculate how to make a+b concentrates and which sources go in which. You need to go into substance selection to add or remove which sources you have available.Curious since I don't know how to calculate actual ppms of the fertilizers...
If its 0-52-34... how does 1 g per 5 gal give 50ppm of p and 60 ppm of k?
To simply answer the question it's the availability of say p or k in the source.Curious since I don't know how to calculate actual ppms of the fertilizers...
If its 0-52-34... how does 1 g per 5 gal give 50ppm of p and 60 ppm of k?
I'll double check when I get home... Is that what you got out of hydrobuddy?Like @Aqua Man said dl hydrobuddy. God send for mixing salts and making stock solutions and reverse engineering commercial nutes.
You can also use http://www.angelfire.com/cantina/fourtwenty/articles/profiles.htm if you want a quick online one
1g per 5gal of MKP gives you 12 ppm of P and 15 ppm of K per gal
Oh fuck nevermind.... I fucked up thats one of the strengths I use to amend my solution. 1g/gal is what I should have said.I'll double check when I get home... Is that what you got out of hydrobuddy?

Yes I was ball parking off memory prob should have made sure. I just get into habhit after a while.yeah that's 60/75 ppm per gal
I know why... Because I use tap water and I have my tap water recorded into my hydrobuddy so it takes the nutrient make up of my tap water into account when calculating.yeah that's 60/75 ppm per gal
The availability like I posted earlier. P and K are an exception. Ferts list them as a combination of P2o5 and P and K20 and K as totals by weight. There are calculations used that will give you the amount of elemental P and K which is immediately available for uptake. for P its P205x0.44=P and for K its K20x0.83=K. This is why i just use a nutrient calculator. I'm to dam lazy to do all this.Ok just curious how mkp which is 52% P and 34% k ends up giving more k than p once diluted in water?
Shouldnt there still be more p than k?
not at home till later.I do a calculator bit it's not the one you reccomend cuz it's only available for windows... I use android
That's why I asked someone to confirm my calculations I did with the calculator app I downloaded
